Patent JP-H05290563-A (JP)
Title: Hermetic structure
Inventor: JINBO MASAKI
IPC: G11B33/12
Filed: 1992-04-10
Abstract: PURPOSE:To enable easy and exact mounting of a packing and to impart good hermeticity by constituting the hermetic structure in such a manner that the packing is pressed by the walls on both sides of the groove of a cover and its central part is deflected when the fitting part of the packing is press fitted into the groove. CONSTITUTION:The packing 35 is pressed to the walls on both sides of the packing detaining part 33 of the groove 32 of the cover 31 when the fitting part 36 of the packing 35 is press fitted into the groove 32. The first and second contact parts 37, 38 are then deflected to the central part and a bending stress acts on the packing 35 to decrease the resistance at the time of insertion of the packing 35. The packing 35 is thus smoothly inserted into the groove 32 until the base end of the packing comes into contact with the bottom of the groove 32. The detachment of the packing 35 from the groove 32 is prohibited by the friction force of the wall surface of the detaining part 33 of the groove 32 generated by the reaction generated by the bending stress and the fitting part 36 of the packing 35. The base end of the packing 35 is so formed as to be gradually narrower as the sectional area is nearer the base end and a space K is therefore formed between the groove 32 and the wall surface at the base end.

Title: Production of heat-resistant, oxidation-resistant carbon material
Inventor: TAWARA TOMOYUKI
IPC: C04B41/89
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To obtain an oxidation-resistant carbon material with improved peeling resistance of its oxidation-resistant coating layer due to heat shock by coating a carbon fiber-reinforced carbon composite material through two layers of specific silicon carbide with a SiO2 sol and heat-treating the coated layer. SOLUTION: A silicon carbide layer is formed, as an adhesion layer, on the surface of a base material of carbon fiber-reinforced carbon composite by the diffusion technique and the carbon composite material is further coated with silicon carbide by the vapor-phase chemical vapor deposition. Finally, SiO2 sol is coated as an outermost layer and heat-treated at >=1,400 deg.C in an inert atmosphere whereby the objective carbon material is prepared. This process for producing carbon material enables the densification of the SiO2 coating layer by its heat treatment at a temperature >=1,400 deg.C at which SiO2 begins softening, when the composite material is coated with SiO2 by the sol-gel technique.  In addition, almost of the SiO2 remaining in cracks is released to the surface layer and the compression stress due to the solid silica on the heat shock is largely reduced to cause no peeling of the oxidation-resistant coating layer.
